I got the wooden version of the Knitpicks Options interchangeable needles. I love the needles, but I'm not a huge fan of the clear plastic pouch-style case they came with. I'm more favorably inclined toward the black binder that the metal needles come with. (Or came with? I just looked and they seem to be using the plastic case for both sets now.)
However from reading postings on the subject, it seems that some people who got the metal Options with the black binder really like the plastic case better.
So why not trade? I'll trade the plastic case I got, for the black binder with the intro set of needle holders. If you're interested, please send me a private message.
P.S. I think this is clear, but to avoid any possible confusion... I am proposing a trade of the cases only, not any of the needles or cables.
